Weird. pcibios_fixup_resources() should have printed things that I
didn't see in your log, which is why I asked...

I -think- your card is just asking too much, more than what we know how
to assign, but that doesn't explain why it used to work. I'll have to
dig a bit more.

You can assign more by changing the "ranges" property in the .dts, I
would expect the 44x PCI code I wrote to automatically adjust.

Cheers,
Ben.
